Abstract

Described are passenger seat assemblies having an impact bracket for a support pin. The support pin may be a component of a monitor assembly. The impact bracket includes a body that defines an aperture and a flex member within the aperture. The flex member defines a support region and a travelling region of the aperture. The flex member retains the support pin in the support region responsive to a load that is less than a minimum impact load, and releases the support pin from the support region into the travelling region responsive to a load that is at least the minimum impact load.

First claim

That which is claimed is:

1. A passenger seat assembly comprising:
a monitor assembly comprising a support pin; and
an impact bracket comprising a body defining an aperture and a flex member within the aperture, wherein the flex member defines an upper end of a support region of the aperture and an upper end of a travelling region of the aperture, wherein the support region is disposed at a non-zero angle with respect to the travelling region, and wherein the flex member is adapted to retain the support pin in the support region responsive to a load that is less than a minimum impact load and release the support pin from the support region into the travelling region responsive to a load that is at least the minimum impact load.

2. The passenger seat assembly of claim 1 , wherein the flex member is configured to maintain a lateral position of the support pin in the support region responsive to the load that is less than the minimum impact load, and wherein the support pin is pivotable within the support region.

3. The passenger seat assembly of claim 1 , wherein the flex member is configured to flex in an upward direction responsive to the load that is at least the minimum impact load such that the support pin is released from the support region into the travelling region.

4. The passenger seat assembly of claim 1 , further comprising a seat back, wherein the impact bracket is supported on the seat back.

5. The passenger seat assembly of claim 1 , wherein the support region comprises a circular profile and wherein the travelling region comprises an elongated profile.

6. The passenger seat assembly of claim 1 , wherein the monitor assembly further comprises a tilting pin, wherein the impact bracket further defines a tilting aperture, and wherein the tilting pin is movable within the tilting aperture such that the monitor assembly is tiltable relative to the impact bracket.

7. The passenger seat assembly of claim 1 , wherein the minimum impact load is 200 lbs.

8. A passenger seat assembly comprising:
a seat back; and
an impact bracket supported on the seat back, wherein the impact bracket comprises a body defining an aperture and a flex member within the aperture,
wherein the flex member defines an upper end of a support region of the aperture and an upper end of a travelling region of the aperture,
wherein the support region is comprises a support aperture having a profile that is complimentary of a support pin; and
wherein the flex member is adapted to retain the support pin within the support aperture of the support region responsive to a load that is less than a minimum impact load and release the support pin from the support region into the travelling region responsive to a load that is at least the minimum impact load, and
a monitor assembly comprising a monitor and the support pin.

9. The passenger seat assembly of claim 8 , wherein the support pin is a first support pin at a first side of the monitor, wherein the monitor assembly further comprises a second support pin at a second side of the monitor opposite from the first side, wherein the impact bracket is a first impact bracket, wherein the passenger seat assembly further comprises a second impact bracket, the second impact bracket comprising:
a body defining an aperture and a flex member within the aperture,
wherein the flex member of the second impact bracket defines an upper end of a support region of the aperture and an upper end of a travelling region of the aperture, and
wherein the flex member of the second impact bracket is adapted to retain the support pin in the support region of the second impact bracket responsive to the load that is less than the minimum impact load and release the second support pin from the support region into the travelling region of the second impact bracket responsive to the load that is at least the minimum impact load.

10. The passenger seat assembly of claim 8 , wherein the impact bracket further defines a tilting aperture, and wherein the tilting aperture is configured to receive a tilting pin such that the tilting pin is movable within the tilting aperture.

11. The passenger seat assembly of claim 8 , wherein the support region comprises a circular profile and wherein the travelling region comprises an elongated profile.

12. The passenger seat assembly of claim 8 , wherein the flex member is configured to maintain a lateral position of the support pin in the support region responsive to the load that is less than the minimum impact load.

13. The passenger seat assembly of claim 8 , wherein the flex member is configured to flex in an upward direction responsive to the load that is at least the minimum impact load and guide the support pin in a downward direction responsive to the load that is at least the minimum impact load.

14. An impact bracket for a passenger seat assembly, the impact bracket comprising:
a body defining an aperture; and
a flex member positioned within the aperture, wherein the flex member defines an upper end of a support region of the aperture and an upper end of a travelling region of the aperture, wherein the support region is disposed at a non-zero angle with respect to the travelling region, wherein the support region comprises a support aperture having a profile that is complimentary of a support pin, and wherein the flex member laterally maintains the support pin of a monitor assembly in the support aperture of the support region responsive to a load that is less than a minimum impact load and is configured to release the support pin from the support region into the travelling region responsive to a load that is at least the minimum impact load.

15. The impact bracket of claim 14 , wherein the body further defines a tilting aperture, wherein the tilting aperture is adapted to receive a tilting pin of the monitor assembly.

16. The impact bracket of claim 14 , wherein the support region comprises a circular profile and wherein the travelling region comprises an elongated profile.

17. The impact bracket of claim 14 , wherein the flex member is configured to flex in an upward direction responsive to the load that is at least the minimum impact load.

18. The impact bracket of claim 17 , wherein the flex member is configured to guide the support pin in a downward direction responsive to the load that is at least the minimum impact load.

19. The impact bracket of claim 14 , wherein the minimum impact load is 200 lbs.
